b riefly or press and hold for longer than two sec­
onds .
.8_ WARNING
- Never turn off the engine before the veh icle
has come to a complete stop. The brake
booster and power steering only work when
the engine is running. If the engine is
off,
you have to use more force when steer ing or
braking . Because you cannot steer and brake
as you usually wou ld, this could lead to acci­
dents and serious injuries.
- Always ta ke the key with you whenever you
leave you r vehicle. Othe rw ise, the engine

could be started or electrical equipment
such as the power windows could be operat­
ed. Th is can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally .
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the eng ine compartment after the engine is
switched
off and there is a r isk of damag ing
the eng ine . For th is reason, let the engine run
for at idle for approximately two minutes be­
fo re shutti ng it
off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ign ition is switched off) for the following
r easons:
- The coolant temperature is increas ing due
to trapped heat.
-If the eng ine is warm and the engine com­
partment a lso heats up from strong sun­
light.

Driving information
Applies to: vehicles with offroad mode
T here is only one right way to drive in difficult
conditions: slo wly and with caution!
Observe the following when driving on unpaved
roads :
.,. On ly driv e in terrain that is suitable for the ve­
hicle and your driving ability. Never take any
unnecessary risks!
.,. Dr ive slowly and caut iously!
.,. Pay attent ion to the
g round cl earan ce of your
veh icle . The clearance may va ry depending on
the load, ground compos ition and the environ­
ment. The g round clearance is reduced for spe­
cial suspension systems, such as sport s uspen­
sion. The dr iver is therefore responsible for de ­
ciding whether a vehicle can handle a specif ic
situation .
.,. Activate the
ESC offroad mode as needed
r=>page90 .
.,. Use the hill de sce nt ass ist when driving down
steep hills
r=> page 91 .
Difficult terrain
When driving in unfamiliar areas and offroad,
drive slowly and keep on the watch for unexpect­
ed obstacles (such as potholes, rocks, tree
stumps , etc .) .
T o prevent th e vehicl e from bottoming out and to
reduce the risk of underbody damage, you should
drive across uneven ground on only one side of
the veh icle so that only two of your wheels cross
the uneven area, instead of driving across the cente r of the uneven area with all four wheels .
Drive quickly through sandy or marshy off-ro ad
sections and do not stop, if at all possible.

- If there is a power failure, the selector lever
will not move out of the P position. The
emergency release can be used if this hap­
pens
¢ page 72.
Driving tips
Starting the engine
~ The selector lever must be in the P or the N po ­
sition.
Starting from a stop
~ Press and hold the brake pedal.
~ Press and hold the lock button in the selector
lever handle, select the desired selector lever
position such as D ¢
page 67 and release the
lock button.
~ Wait a moment until the transmission shifts .
You will notice a slight movement when the gear engages .
~ Release the brake pedal and press the accelera-
tor pedal ¢,&. .
Various convenience functions are available for
starting on hills
¢ page 65 .
Stopping temporarily
~ Press the brake pedal to stop the vehicle, for
example at a traffic light. Do not press the ac­
celerator pedal when doing this .
~ To prevent the vehicle from rolling when you
start driving, set the parking brake when stop­
ping on steep hills ¢
8. and ¢0.
~ The parking brake will release automatically
and the vehicle will start moving once you press
the accelerator pedal.
Stopping/parking
If the selector lever is not in the P position when
you open the driver's door, the vehicle could roll.
In vehicles with a convenience key*, the message
Shift to P and turn off ignition, or vehicle can
roll away
appears.
~ Press and hold the brake pedal¢,&. .
~ Set the parking brake .
~ Select the P selector lever position .
Driving
Under certain circumstances, (such as driving in
the mountains or towing a trailer), it may be use­
ful to switch temporarily to the manual shift pro­
gram in order to adjust the gears to the driving
conditions by hand
¢page 70.
On inclines, activate the parking brake first and
then move the selector lever to the P position
¢
page 64. This prevents the locking mechanism
from being loaded too heavily and will make it
easier to move the selector lever out of the P po ­
sition.
A WARNING
= -- The vehicle can roll even when the engine is
switched off.
- Unintended vehicle movement can lead to
serious injuries .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake in all selector
lever positions (except P) when the engine is
running.
- Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the risk of an accident
increases because the vehicle will start to
move immediately, even if the parking brake
is set.
- To reduce the risk of an accident, do not
press the accelerator pedal when changing
the selector lever position while the vehicle
is stationary and the engine is running.
- Never engage the R or P selector level posi­
tions while driving. It could cause a crash.
- Before driving down a steep slope, reduce your speed and shift into a lower gear in tip­tronic mode.
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and substantially ..,.

Driving
reduces braking performance, increases
braking distance or causes complete failure
of the brake system.
- If you must stop on an incline, always hold
the vehicle in place with the foot brake or
parking brake to prevent it from rolling
back.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload . The . indicator light turns on
and a message appears~
page 71 when
the clutch is overloaded.
- Read and following all WARNINGS
9 &, .
(D Note
-When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­ lected . This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped while the selector lever is in the
N position will damage the automatic trans­
mission, because it is not lubricated under
those circumstances ~
page 205, Towing
with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions su ch as frequent starts, creeping for a
long time, or stop-and-go traffic. If the.
indicator light turns on, stop the vehicle at
the next opportunity and let the transmis­
sion cool down
~ page 71.
H ill descent contr ol
The hill descent control system assists the driver
when driving down hills .
Hill descent contro l is activated when the selec­
tor lever is in the Dor S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach­
ieve d at the time of braking, within physical and
70
technical limitations. If may still be necessary to
adjust the speed with the brake pedal.
Hill descent control switches off once the hill lev­
els out or you press the accelerator pedal.
&_ WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes .
Manual shifting (tiptronic mode }
The tiptronic mode allows the driver to shi~ the
gears manually .

Intelligent Technology Electronic stabilization
control (ESC)
Description
Ele ctronic stabilization control (ESC) supports
driver safety . It reduces the risk of slipping and
improves d riving stability. ESC detects critica l sit ­
uations such as the vehicle oversteering and un­
dersteer ing or the wheels are spinning. The vehi­
cle is stabilized by apply ing the brakes or reduc ­
ing engine torque . When the ESC engages, the
G1 indicator light b links in the instrument clus­
ter.
T he follow ing systems are integrated in the ESC:
Ant i-loc k bra king s ystem (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Brak e a ssist s ystem
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
unti l the dangerous sit uat io n is ove r.
Anti-Slip Regulation (ASR )
ASR reduces eng ine power when the drive wheels
begin spinning and ad apts the force to the road
conditions . This makes it easier to start, acceler ­
ate and dr ive up hills .
Electronic differential lock (EDL )
The EDL applies the brakes to a whee l that starts
spinning and transfers the drive power to the
other driving wheel or wheels ( if the veh icle is
equ ipped w ith all wheel dr ive*) . This function is
n ot available at higher speeds .
0 ~ In extreme cases, EDL automatically switches off
~ to keep the brake on the braked wheel from over-N

will swi tch on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lps to s tabilize the vehicle by cha nging
t h e steer ing torque .
Selective wheel torque control
Se lective wheel torque control is used when driv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both wheels on the i nside of the
c ur ve are braked se lectively as needed. This al­
lows mo re prec ise dr iving in c urves .
Automatic post -collision braking system
The "automat ic post -collis ion braking system"
can help to reduce the risk of sliding and of addi­
tiona l co llisions after an accident.
If the a irbag
contro l modu le detects a collision above a certa in
vehicle speed, the ve hicle is br ake d by the ESC.
The vehicle does not brake automatically if:
- the dr iver presses the acce lerator pedal, or
- the bra king fo rc e generated by the pressed
brake pedal is greater than the braking force
that would be in itiated by the system, or
- the ESC, the brake system or the veh icle electri­
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
phys ica l laws. This is especially impo rtant
on slippery or wet roads. If the systems be­
gi n a cting to s tabilize yo ur vehicle, you
should immedi ately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk o f a collis ion.
- Please note the r isk of a coll is ion increases
when dr iv ing fast, especially t hrough curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre ­
vent co llisions - there is st ill a risk of acci­
dents!
89

A WARNING
You should only switch offroad mode on or
switch ESC/ ASR off if your driving abilities
and the traffic conditions perm it. There is a
risk of s lid ing .
- The stabilization function is limited when
offroad mode is switched on . The driving
wheels could spin and the vehicle could
swerve, especially on slick or s lippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
Hill descent assist
Appl ies to: vehicles with hill hold assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig. 97 Center console : hill descent assist butto n
• To switch the hill descent assist on, press the
~ button in the center console c} fig. 97. The
LED in the button turns on.
• Press the button again to switch it off. The LED
in the button turns off .
Hill descent assist brakes all four whee ls auto ­
matically in order to limit speed when driving ei­
ther forward or reverse on hills with a grade up to
approximately 50% .
When hill descent assist is on, the speed your ve­ hicle was traveling when it entered the hill is
maintained . It is only possible to switch on the
assist when driving slower than 37 mph (60 km/
h). The assist begins shortly after you start driv-
e '.:: ing and continues up to approximate ly 19 mph
N r--. (30 km/h) . T he driver can increase or decrease N .... 0 0 ::, (X)
Intelligent Technology
the vehicle speed within these limits by pressing
the accelerator or brake pedal.
However, there must be enough tract ion. Hill de­
scent assist
cannot function as expected, if for
example the hill is icy or if the surface is loose
¢,&. .
A blinking indicato r light. in the instrument
cluster will indicate if the system if actively regu­
lating a specific speed up to approximately
19 mph (30 km/h). The indicator light stays on
continuously when in the ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h) . The system is
then in ready-mode . This is indicated by the LED
in the button turning on. The system automat i­
cally switched off when you drive faster than 37
mph (60 km/h) . The LED will also turn off in this
scenario .
Hill descent assist is automatically activated un­
der the following conditions:
- the LED in the button turns on
- the vehicle speed is lowe r than 19 mph (30 km/
h)
- the incline angle is at least around 10%
A WARNING
-
-Always adapt your speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident.
- The hill descent assist system cannot over­
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions .
- Hill descent ass ist may not be able to hold
your vehicle at a constant speed under all
conditions while dr iving on a hill (for exam ­
p le if ground under the vehicle is loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km) . They
must be "broken in" first . However, you can
IJ,,
91

Intelligent Technology
compensate for the slightly reduced brak ing
force by pressing firmly on the brake peda l. Avoid
heavy b raking during the break -in per iod .
Wear
Brake pad wear depends largely on the way the
veh icle is driven and on operat ing cond it ions.
This is especially t rue if you are driving frequently
in the city and on c urves or with a sporty driving
style.
Operating noise
Noises may occur when br aking depend ing on the
speed, b raking force and outs ide cond itions such
as temperature and humidity.
Effect of water or road salt
I n ce rtain s ituations, fo r example after driving
through water, in heavy ra in, afte r ove rnig ht con­
densat ion or after washing your car, the braking
effe ct can be red uced by moisture or ice on the
b rake rotors and brake pads. The brakes must be
"dr ied" first with a few careful brake applica ­
tions.
At highe r speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The laye r of salt
on the brake rotors and brake pads must be worn
off first when t he brakes a re applied ¢ ,& .
Corros ion
L eaving the vehicle par ked for long periods of
time, low mi leage and avo id ing heavy brak ing
